Description

Technical Field

[0001] The invention relates to the technical field of retaining walls, and in particular to an assembled retaining wall for roadbed support. Background Art

[0002] As a key building structure to prevent soil collapse and maintain soil stability, retaining walls play an indispensable role in many important fields. In construction projects, they provide support for various buildings to ensure their safety and stability; in garden projects, retaining walls divide space, shape terrain, and add a sense of layering and three-dimensionality to the landscape; in water conservancy projects, they resist the erosion of river banks by water flow, protecting water conservancy facilities and the surrounding ecological environment; in highway projects, retaining walls ensure the stability of road slopes and provide safe passage conditions for vehicles; in bridge projects, retaining walls and bridge structures cooperate with each other to jointly maintain the stability of the bridge foundation.

[0003] Traditional retaining walls usually use on-site construction technology, which means that a series of processes such as formwork, cast-in-place, and maintenance are required. These processes are not only time-consuming, but also seriously affect the progress of the project. For example, in the formwork process, a lot of manpower and time are required to build and adjust the formwork, and the accuracy and stability of the formwork are difficult to guarantee, which is prone to deviation and deformation, affecting the quality of the retaining wall. During the cast-in-place process, the mixing, transportation, and pouring of concrete need to be carried out on-site, which is not only inefficient, but also easily affected by factors such as weather and traffic, resulting in construction interruptions and delays. The maintenance process is even longer and takes several days or even weeks. During this period, the construction site needs to be closed and protected, affecting the surrounding traffic and environment.

[0004] In addition, the traditional on-site retaining wall will have a great impact on the construction site and the surrounding environment during the construction process. On the one hand, the noise, dust and construction waste generated by the construction will pollute and interfere with the lives and environment of the surrounding residents. On the other hand, the stacking of a large number of construction equipment and materials will occupy a large amount of space, affecting the surrounding traffic and the construction of other projects. Moreover, the quality of the retaining wall constructed on site is difficult to guarantee, and it is prone to cracks, leakage and other problems, which require later maintenance and reinforcement, increasing the cost and difficulty of the project.

Even when the soil pressure is high, the retaining wall can maintain a stable structure and provide reliable protection for the roadbed support. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0024] Reference Figure 1 to Figure 6 , which is the first embodiment of the present invention, proposes an assembled retaining wall for roadbed support, which is built with concrete blocks 1; the concrete block 1 has a first wall 11 and a second wall 12, and the first wall 11 and the second wall 12 are arranged opposite to each other laterally; it also has a third wall 13 and a fourth wall 14, the third wall 13 and the fourth wall 14 are arranged opposite to each other longitudinally, and respectively connect the first wall 11 to the second wall 12; the first wall 11 has a first clamping portion 111, and the second wall 12 has a first plug-in portion 121; the third wall 13 has a second clamping portion 131, and the fourth wall 14 has a second plug-in portion 141; the first plug-in portions 121 of two laterally adjacent concrete blocks 1 abut against the first clamping portion 111; the second plug-in portions 141 of two longitudinally adjacent concrete blocks 1 abut against the second clamping portion 131.

[0025] In this embodiment, in order to solve the problems of long construction period and high construction difficulty of cast-in-place concrete retaining wall in the related art, a prefabricated retaining wall for roadbed support is designed. First, a plurality of concrete blocks 1 are produced in the factory in strict accordance with the design specifications. A first clamping portion 111 is created on the first wall 11 of these concrete blocks 1, and its shape and size are accurately calculated to ensure that it can perfectly fit with the first plug-in portion 121 on the second wall 12. Similarly, the second clamping portion 131 on the third wall 13 and the second plug-in portion 141 on the fourth wall 14 also have a high degree of precision. At the construction site, the construction workers put the concrete blocks 1 in place one by one. When making a horizontal connection, the first plug-in portion 121 of a concrete block 1 is inserted into the first plug-in portion 111 of the adjacent concrete block 1 to ensure that the two are closely abutted without leaving a gap. The same method is also used for the longitudinal connection to accurately dock the second plug-in portion 141 with the second clamping portion 131. As the concrete blocks 1 are connected one by one, the prototype of the retaining wall gradually emerges.

[0026] The advantage is that this connection method of snap-on and plug-in greatly simplifies the assembly process of the retaining wall. Construction workers do not need to use a large number of bolts to connect, but only need to splice the concrete blocks 1 in the correct direction. This not only improves construction efficiency, shortens the project cycle, but also reduces construction costs. At the same time, this connection method can provide stable support in all directions, effectively preventing the retaining wall from loosening and shifting during use. Even when the soil pressure is high, the retaining wall can maintain a stable structure and provide reliable protection for roadbed support.

[0027] Furthermore, the concrete block 1 also has a fifth wall 15 and a sixth wall 16; the fifth wall 15 and the sixth wall 16 are arranged vertically opposite to each other, and respectively connect the first wall 11 to the second wall 12, the third wall 13, and the fourth wall 14; the fifth wall 15 has a first mounting groove 151, and the sixth wall 16 has a third plug-in portion 161 and a third clamping portion 162, and also includes a clamping rod 2 rotatably arranged in the first mounting groove 151, and one end of the clamping rod 2 has a fourth plug-in portion 21. After the fifth wall 15 and the sixth wall 16 of two vertically adjacent concrete blocks 1 are vertically close, the third plug-in portion 161 abuts against the other end of the clamping rod 2, so that the clamping rod 2 rotates and the fourth plug-in portion 21 abuts against the third clamping portion 162.

[0028] In this embodiment, the fifth wall 15 and the sixth wall 16 of the concrete block 1 play a key role in the vertical connection of the retaining wall. The first mounting groove 151 on the fifth wall 15 provides an installation position for the clamping rod 2. The clamping rod 2 is accurately installed in the first mounting groove 151 during factory production, and it is ensured that it can rotate freely. When vertical assembly is performed, the construction personnel slowly bring the fifth wall 15 and the sixth wall 16 of the two concrete blocks 1 closer. At this time, the third plug-in portion 161 on the sixth wall 16 first contacts one end of the clamping rod 2, and as the process of continuing to approach, the clamping rod 2 is pushed to rotate. When rotated into place, the fourth plug-in portion 21 at one end of the clamping rod 2 is tightly abutted against the third clamping portion 162 on the sixth wall 16 to complete the vertical connection. This process requires the construction personnel to operate carefully to ensure the accurate docking of each component.

[0029] The advantage is that the reliability of the vertical connection is increased, so that the retaining wall can withstand greater soil pressure in the vertical direction. The setting of the clamping rod 2 provides additional support for the vertical connection, effectively preventing separation or dislocation between vertically adjacent concrete blocks 1. This connection method improves the overall stability of the retaining wall, and can ensure the safety and reliability of the retaining wall even when the geological conditions are relatively complex or the soil pressure is uneven.

[0030] Furthermore, the fifth wall 15 also has a first groove 152 , and the sixth wall 16 also has a first protrusion 163 ; after the fifth wall 15 and the sixth wall 16 of two vertically adjacent concrete blocks 1 abut against each other, the first groove 152 abuts against the first protrusion 163 .

[0031] In this embodiment, during the design and production process of the concrete block 1, the fifth wall 15 and the sixth wall 16 are specially processed. A first groove 152 is processed on the fifth wall 15, and its shape and depth are strictly designed. At the same time, a first protrusion 163 is correspondingly provided on the sixth wall 16. When vertically assembling, the construction personnel accurately align the fifth wall 15 and the sixth wall 16 of the two concrete blocks 1 so that the first groove 152 and the first protrusion 163 abut against each other.

[0032] The advantage is that the tightness of the vertical connection is further enhanced, and the relative displacement between the vertically adjacent concrete blocks 1 is effectively prevented. The first groove 152 and the first protrusion 163 cooperate like the parts of a puzzle, fitting together to form a whole in the vertical direction of the retaining wall. This connection method improves the overall structural stability of the retaining wall and can better resist the pressure of the soil and the influence of the external environment.

[0033] Furthermore, the surface of the first protrusion 163 is an arc surface, and the shape of the first groove 152 is adapted to the first protrusion 163 .

[0034] In this embodiment, in order to improve the matching effect between the first protrusion 163 and the first groove 152, the surface of the first protrusion 163 is designed to be a curved surface. At the same time, the shape of the first groove 152 is also precisely designed according to the curved surface of the first protrusion 163, so that it can fit perfectly with the curved surface. During the assembly process, the design of the curved surface makes it easier for the first protrusion 163 to dock with the first groove 152. The construction personnel only need to gently push the concrete block 1, and the first protrusion 163 can slide into the first groove 152 along the curved surface, which greatly improves the convenience of construction.

[0035] The advantage is that the curved surface design is not only easy to install, but also can disperse stress to a certain extent. When the retaining wall is subjected to soil pressure, the curved surface can evenly disperse the pressure to the surrounding concrete blocks 1, reducing the risk of damage caused by stress concentration. This design makes the retaining wall more stable and reliable during long-term use, extending the service life of the retaining wall.

[0036] Furthermore, the first protrusion 163 and the first groove 152 coincide with the center of the concrete block 1 .

[0037] In this embodiment, during the production process of the concrete block 1, high-precision molds and advanced production processes are used to ensure that the first protrusion 163 and the first groove 152 are accurately aligned with the center of the concrete block 1. From the design stage, the positions of each component are strictly calculated and planned. During the production process, the positions of the first protrusion 163 and the first groove 152 are accurate through precise positioning and control. During the assembly process, the construction personnel also need to carefully check and adjust the position of the concrete block 1 to ensure that the first protrusion 163 and the first groove 152 can be accurately docked.

[0038] The advantage is that this design makes the retaining wall more evenly stressed in all directions. When the soil pressure acts on the retaining wall, since the first protrusion 163 and the first groove 152 coincide with the center of the concrete block 1, the pressure can be evenly transmitted to each concrete block 1, avoiding the situation where the local force is too large. This improves the overall stability and bearing capacity of the retaining wall, allowing the retaining wall to better withstand the pressure of the soil and the influence of the external environment. At the same time, it also facilitates quality control during production and assembly, and reduces the problem of loose connection or unstable structure caused by position deviation.

[0039] Furthermore, the concrete block 1 has a first cavity 17 at its center, and the first cavity 17 communicates with the first protrusion 163 and the first groove 152 .

[0040] In this embodiment, during the design and production stage of the concrete block 1, the first cavity 17 is carefully set in the center of the concrete block 1, taking full account of the convenience of transportation and the need for structural strengthening. From a design perspective, the size and shape of the first cavity 17 are determined by precise calculation, and its weight is reduced as much as possible under the premise of ensuring the basic strength of the concrete block 1. In the production process, advanced concrete pouring technology is adopted to ensure the molding quality of the first cavity 17 and the structural stability of the concrete block 1 as a whole. When transported to the construction site for retaining wall assembly, after several concrete blocks 1 are abutted against each other according to the design requirements to complete the preliminary retaining wall structure, the concrete pouring equipment is prepared. Slowly inject concrete into the first cavity 17. During the pouring process, strictly control the flow rate and pouring amount of concrete to ensure that the concrete fully fills the first cavity 17 and does not produce cavities or bubbles. After the concrete solidifies, the various concrete blocks 1 inside the retaining wall are connected as a whole by concrete.

[0041] The advantage is that, on the one hand, the design of the first cavity 17 greatly reduces the weight of the concrete blocks 1, which makes the transportation process more convenient and efficient, and reduces the transportation cost. For some engineering construction in inconvenient transportation or remote areas, the lightweight concrete blocks 1 can reduce the difficulty and cost of transportation. At the same time, at the construction site, the lighter concrete blocks 1 are also convenient for construction personnel to carry and operate, which improves the construction efficiency. On the other hand, after the assembly is completed, concrete is poured into the first cavity 17 to make the retaining wall a whole, which greatly enhances the stability of the overall structure. After solidification, the concrete can tightly connect the various concrete blocks 1 together, enhancing the bearing capacity of the retaining wall against soil pressure. Even under complex geological conditions or under greater soil pressure, this retaining wall reinforced with concrete can remain stable and reliable, extending the service life of the retaining wall and providing a more solid guarantee for roadbed support.

[0042] Furthermore, it also includes a connecting rib 3, both ends of which have external threads, the connecting rib 3 is arranged inside the first cavity 17, and the connecting rib 3 coincides with the center of the concrete block 1; the connecting nut 4 is threadedly arranged at one end of the connecting rib 3, and after the fifth wall 15 and the sixth wall 16 of two vertically adjacent concrete blocks 1 abut, the end faces of the two connecting ribs 3 abut, and the connecting nut 4 is rotated to limit or release the position of the two connecting ribs 3.

[0043] In this embodiment, the connecting rib 3 is an important component of the vertical connection of the retaining wall. The connecting rib 3 is made of high-strength steel, and both ends are processed with external threads. During the production process of the concrete block 1, the connecting rib 3 is accurately set inside the first cavity 17 and made to coincide with the center of the concrete block 1. The connecting nut 4 is also made of high-strength material, and the thread matches the external thread of the connecting rib 3. When the fifth wall 15 and the sixth wall 16 of two vertically adjacent concrete blocks 1 abut, the end faces of the two connecting ribs 3 also contact each other. At this time, the construction personnel screw the connecting nut 4 on one end of the connecting rib 3, and gradually tighten the connecting nut 4 by rotating it, thereby limiting the position of the two connecting ribs 3 and achieving further reinforcement of the vertical connection.

[0044] The advantage is that the arrangement of the connecting ribs 3 and the connecting nuts 4 further enhances the stability of the vertical connection. When the soil pressure is high or the external environment is harsh, the connecting ribs 3 can withstand large tensile and shear forces, effectively preventing the vertically adjacent concrete blocks 1 from separating.

[0045] Furthermore, the connecting nut 4 has a first gear tooth 41 on the outside, and the concrete block 1 also has a first slide groove 18, which runs through the concrete block 1; the sliding rack 5, after a number of concrete blocks 1 abut against each other, a number of first slide grooves 18 are connected to each other to form a slideway 181, and the sliding rack 5 is slidably set in the slideway 181, and the sliding rack 5 is meshed with the first gear tooth 41, and the sliding rack 5 drives the connecting nut 4 to rotate after sliding.

[0046] In this embodiment, in order to improve the installation efficiency and operation convenience of the connecting nut 4, a first gear 41 is provided on the outer side of the connecting nut 4. At the same time, a first slide groove 18 is provided on the concrete block 1, and the first slide groove 18 runs through the concrete block 1, and its position and size are carefully designed to correspond to the position of the connecting nut 4. When a plurality of concrete blocks 1 abut against each other, a plurality of first slide grooves 18 are connected to each other to form a slideway 181. A sliding rack 5 is prepared, which is made of high-strength material, and the width and thickness match the slideway 181. The sliding rack 5 is slid into one end of the slideway 181. During the sliding process, since the sliding rack 5 is meshed with the first gear 41, its movement drives the connecting nut 4 to rotate. The sliding rack 5 is continuously pushed until the connecting nut 4 is tightened in place, so as to further strengthen the vertical connection. When the connecting nut 4 is installed, the sliding rack 5 can be slid out from the other end of the slideway 181. At the same time, the design of the slideway 181 has another important function in the use of the retaining wall. When it is necessary to install a drain pipe, the slideway 181 can be used as an installation hole. According to the specifications and installation requirements of the drain pipe, the slideway 181 is processed and installed at the corresponding position, so that the drain pipe can be accurately installed in the retaining wall, ensuring that the retaining wall can effectively drain water during use and preventing water accumulation from damaging the retaining wall structure.

[0047] The advantages are that, firstly, the operation of the sliding rack 5 greatly improves the installation and disassembly efficiency of the connecting nut 4, saving construction time. The movement of the sliding rack 5 can adjust multiple connecting nuts 4 at the same time, avoiding the cumbersome process of screwing the connecting nuts 4 one by one, especially for large-scale retaining wall construction projects, which can significantly improve the construction efficiency and shorten the project period. Secondly, after completing the installation task of the connecting nut 4, the slide 181 can also be used as the installation hole for the drain pipe, giving full play to its multifunctional role. This design makes the drainage system of the retaining wall more perfect, can timely and effectively remove the accumulated water in the wall, reduces the impact of the accumulated water on the structural stability of the retaining wall, and extends the service life of the retaining wall. At the same time, it also reduces the process of additional drilling for the installation of the drain pipe during the construction of the retaining wall, improving the convenience of construction and the overall engineering efficiency.

[0048] Furthermore, the first plug-in portion 121 and the second plug-in portion 141 are both T-shaped, and the shapes of the first clamping portion 111 and the second clamping portion 131 are respectively matched with the first plug-in portion 121 and the second plug-in portion 141 .

[0049] In this embodiment, during the design process of the concrete block 1, the first plug-in portion 121 and the second plug-in portion 141 are designed to be T-shaped. At the same time, the shapes of the first clamping portion 111 and the second clamping portion 131 are also accurately designed according to the first plug-in portion 121 and the second plug-in portion 141, respectively, to ensure that the two can perfectly match. During the production process, high-precision molds and processing techniques are used to ensure the dimensional accuracy and surface quality of the T-shaped plug-in portion and the clamping portion. During the assembly process, the construction personnel splice the concrete block 1 in the correct direction so that the T-shaped plug-in portion is accurately inserted into the clamping portion to ensure that the two are tightly combined without leaving any gaps.

[0050] The advantage is that the T-shaped connection structure is more solid and can effectively prevent lateral and longitudinal displacement. The T-shaped shape design allows the plug-in part to form a stable support in the clamping part, and the stability of the connection can be maintained even when the soil pressure is high. This structure improves the overall stability of the retaining wall and can better withstand the pressure of the soil and the influence of the external environment. At the same time, this structure is also easy to produce and install. The T-shaped plug-in part and the clamping part can adopt standardized production processes to improve production efficiency. During the installation process, the construction personnel only need to insert the plug-in part into the clamping part, without the need for complex adjustments and fixation, which reduces the difficulty of construction.

[0051] Furthermore, a plurality of concrete blocks 1 are connected to each other to form a wall surface, a wall bottom and a handrail.

[0052] In this embodiment, during the construction of the retaining wall, the number and specifications of the concrete blocks 1 are reasonably selected according to the engineering design requirements. The construction personnel place several concrete blocks 1 against each other, and form the wall surface, the wall bottom and the armrest through precise arrangement and combination. When forming the wall surface, the flatness and verticality of the concrete blocks 1 are ensured to ensure the appearance quality and stability of the retaining wall. The concrete blocks 1 at the bottom of the wall need to withstand greater pressure, so special attention should be paid to their strength and stability during selection and installation. The design of the armrest should be reasonably planned according to the soil pressure and the height of the retaining wall to ensure that it can provide sufficient supporting force. During the construction process, it is also necessary to pay attention to the tightness of the connection between the various parts to ensure the overall structural stability of the retaining wall.

[0053] The advantage is that it can be flexibly designed and constructed according to different engineering requirements, and can adapt to various terrains and usage conditions. Whether in mountainous areas, plains or urban construction, this prefabricated retaining wall can be customized and constructed according to specific terrain and engineering requirements. At the same time, the prefabricated construction method can improve construction efficiency and reduce the impact of on-site construction on the environment. Since the concrete blocks 1 are produced in the factory, the quality can be effectively controlled and the noise, dust and other pollution during the construction process can be reduced. In addition, this construction method can also shorten the project cycle, reduce project costs, and bring greater economic and social benefits to engineering construction.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
